COMBINED. BOOK AND'INDEX.

SPECIFICATION forming part of Letters Patent No. 383,543, dated May 29,1888.

Application filed March 7, 1887. Serial No. 230,018. (No model.)

To aZZ whom it may concern:

Be it known that I, ROBERT M. RIGBY, a citizen of the United States,residing at Kan sas City, Jackson county, Missouri, have inventedcertain new and useful Improvements in Combined Book and Index, of whichthe following is a specification.

This invention relates generally to that class of combined book andindex wherein the index, formed independent of the book, is connectedwith the book in such manner as to enable it to be extended or withdrawnfrom within the book, so that both the index and book may be referred tosimultaneously and the leaves of each be turned without interfering withor overlapping theleaves of the other, and when not in use he confinedbetween the book-covers. It relates more particularly, however, to amode of connecting the index with the book so as to facilitate a moreready and convenient handling thereof.

To this end the present invention consists, essentially, in uniting oneedge of one of the leaves of the index to the edge of one of the leavesof the book, whereby the index may be confined or withdrawn from betweenthe covers of the book for reference or other use.

As a clearer understanding of the present improvement'may be best had bya detailed description of apractical embodiment thereof, all preliminarydescription will be omitted and such detailed description will now begiven in connection with the accompanying drawings, in which- Figure 1is a perspective view of the combined book and index united, inaccordance with the present invention, and illustrating the index in theact of being withdrawn or extended from within the book. Fig. 2 is anend elevation of the same, the index being shown in its'normal positionwithin the book. Fig. 3 is a like view illustrating the index withdrawnor extended from within the book in position for use; and Fig. 4, aperspective view showing an operation of the improved index, to behereinafter particularly referred to.

The book A, with which an index is to be combined, is provided with anyordinary or suitable covers, B, and may be a letterpress copy, account,or other book. The index D,

of any form the requirements of its use may dictate, consists of anumber of leaves bound in book form, that are provided or not alongtheir edges with suitable referencetags, E, bearing letters arrangedthereon in alphabetical order, as shown, which index-leaves may beconfined or not between suitable covers, F.

The book and index are combined by uniting the edge of one of theleavesC of the book A (it may be either its first or last leaf, according towhether theindexis placed atthe front or rear of the book, andpreferably the latter) to the edge of either the first or last leaf, orof the front or back of the cover F of the index D. The union betweenthe two leaves or the book-leaf and the indexcover may be effected byany suitable means, so as to providea flexible connection, d,therebetween, and thus enable the index D' to be folded between saidleaf C and the book-cover, as in Fig. 2, or be unfolded therefrom, so asto extend beyond the book and cover, as in Fig. 3.

While it is obvious that the initial or last leaf, C, of the book A maybe used for connecting the index thereto, the book will preferably beprovided with a special leaf of consider able strength, and bound orunited firmly to the book-covers B, as at a point, a, or at such a pointdistant from the edge of the cover B as will provide room enough toreceive theindex when folded therebctwcen, as in said Fig. 2, from whichit will be seen that when it is desired to consult the index D its frontedge may be grasped between the fingers and be withdrawn from betweenthe leaf C and the book-cover B, as in Fig. 1, until it is drawn clearof the book-cover, and its leaf or its cover F,from occupying a positionfolded on the con nection 01, extends therefrom, as shown in Fig. 3,when the index may be readily referred to.

\Vhen it is desired to return the index D to its normal position betweenthe covers of the book A, the improved structure enables the user, inwhatever position the major portion of the leaves of the book may be, tosimply push on the edge of the index D, and its leaf or cover F willcommence to close down upon it, as in Fig. 4, and, bending on theconnection d, will slide wholly between the leaf 0 and the book-cover B,as in Fig. 2.

From the foregoing it will be apparent that 2 4 seams if the index D bebound within covers, and the connection d be made between said leaf 0 ofthe book and one edge of the index-cover, as F, in withdrawing the indexfrom between the leaf 0 and the book-cover B for reference or use theindex-cover will be opened simultaneously with the withdrawal of theindex, presenting the notched edge or referencetags E of theindex-leaves for immediate use without the necessity of opening theindex after it has been withdrawn.

It may be remarked in passing that the leaves 0 and F might be formed bya single leaf doubled or folded on the line d to form the requiredconnection, one edge being firmly attached to the rear of the book-coverand the other edge united to the index-back, as is obvious; and it mayalso be remarked that while the supplemental book D has been termed anindex, it obviously maybe any other class of reference-book or guidewhich it may be desired to refer to in connection with the book proper.So, too, the index or supplemental book D may be so connected with thebook proper that it may be referred to without neoessarily withdrawingit therefrom.

What I claim is- In a combined book and index, the combi nation, with abook provided with a leaf, 0, free of the book-cover, to its rear edge,of an index provided with a leaf or cover, F, the free edge of thelatter being flexibly united to the free edge of the leaf 0, whereby theindex is independent of the book-cover and may be inserted and confinedbetween the book-cover and the leaf 0, with the front edges of its
